Excessive Daytime Sleepiness

Struggling to stay awake, stay focused, or feel alert during the day?

Excessive daytime sleepiness can be a sign of insufficient sleep, a sleep disorder, medication effects, or another underlying health issue. Dallas Sleep Health can evaluate your symptoms and help determine the appropriate next step.

What Is Excessive Daytime Sleepiness?

Excessive daytime sleepiness (EDS) is more than simply feeling tired. It refers to an ongoing tendency to feel unusually sleepy or to struggle to stay awake and alert during the day.

You may notice excessive sleepiness while reading, watching television, working, attending meetings, or during other normally wakeful activities.

Persistent daytime sleepiness can have many possible causes, including insufficient sleep, sleep disorders, medications, medical conditions, and irregular sleep schedules. A sleep evaluation can help determine whether an underlying sleep problem may be contributing to your symptoms.

Sleepiness and Fatigue Are Not Always the Same

Sleepiness

Sleepiness is a tendency to feel drowsy, fall asleep, or struggle to remain awake and alert.

Fatigue

Fatigue is more often described as a lack of energy, motivation, or physical and mental stamina.

A person can experience one, the other, or both. Understanding the difference can help your sleep specialist determine what may be contributing to your symptoms.

What Can Cause Excessive Daytime Sleepiness?

There are many possible reasons someone may experience excessive daytime sleepiness.

Sleep Apnea

Obstructive sleep apnea can repeatedly disrupt breathing and sleep throughout the night. Some people may not realize their sleep is being disrupted but may experience excessive sleepiness, difficulty concentrating, or reduced daytime alertness.

Not Getting Enough Sleep

Consistently getting less sleep than your body needs can make it difficult to remain alert during the day. Sleep duration, sleep quality, and your regular sleep schedule can all affect daytime alertness.

Other Sleep Disorders

Other sleep disorders can also contribute to excessive daytime sleepiness. Depending on your symptoms, your sleep specialist may evaluate for conditions affecting your ability to obtain restorative sleep or maintain normal wakefulness.

Irregular Sleep Schedules

Shift work, changing sleep schedules, and disruptions to your normal sleep-wake cycle can make it harder to stay alert during the day.

Medications or Medical Conditions

Certain medications and medical conditions can contribute to daytime sleepiness. Your sleep specialist can review your medical history and medications as part of your evaluation.

Stress, Mood & Lifestyle Factors

Stress, sleep habits, daily routines, and other lifestyle factors may also affect your sleep and daytime alertness. Understanding the full picture is an important part of determining what may be contributing to your symptoms.

Signs You May Have Excessive Daytime Sleepiness

How Do We Evaluate Excessive Daytime Sleepiness?

At Dallas Sleep Health, we look beyond daytime sleepiness itself to understand what may be contributing to your symptoms.

1
Review Your Symptoms

We discuss when your sleepiness occurs, how often it happens, and how it affects your daily life.

2
Review Your Sleep History

We look at your sleep schedule, sleep duration, nighttime symptoms, sleep quality, and other relevant factors.

3
Consider Possible Causes

Your sleep specialist may evaluate whether a sleep disorder, medication, medical condition, irregular sleep schedule, or another factor could be contributing.

4
Sleep Testing When Appropriate

Depending on your symptoms and clinical evaluation, sleep testing may be recommended to evaluate for an underlying sleep disorder.

5
Personalized Treatment Plan

Once the likely cause is identified, your sleep specialist can discuss appropriate treatment and next steps.

Treatment Depends on the Cause

There is no single treatment for excessive daytime sleepiness.

Treatment depends on what is causing or contributing to your symptoms.

If an underlying sleep disorder is identified, treatment may include approaches appropriate for that condition. For example, obstructive sleep apnea may be treated with PAP therapy, oral appliance therapy, weight-management strategies when appropriate, or other treatments for selected patients.

Your sleep specialist can help determine which approach is appropriate based on your diagnosis and individual circumstances.

Why Address Excessive Daytime Sleepiness?

Persistent daytime sleepiness can affect more than your energy level. It may make it harder to stay focused, be productive, maintain relationships, and perform everyday activities safely.

Finding the underlying cause can help you take the right steps toward better sleep and a better quality of life.

When Should You See a Sleep Specialist?

Consider a sleep evaluation if daytime sleepiness is persistent, interferes with your daily activities, or occurs even when you believe you are getting adequate sleep.

You should also discuss your symptoms with a sleep specialist if daytime sleepiness occurs along with:
